Source of electrical current, something to transport the current, and something that causes current to flow through a conductor are all required for ________________.

• A. current to flow through a conductor
• B. a completed circuit
• C. electrical power
• D. ground fault

Answer: (A)

Current flows when there is a source of electrical potential, a path to carry the charges, and something that drives the charges through the conductor. When those three pieces are present, the result is that current moves through the conductor. The emphasis here is on the actual flow of charge in the conductor, not merely the loop being closed. A completed circuit describes the closed path, which enables flow, but the statement points to the act of current moving through the conductor itself. Electrical power is the energy delivered by the current, which depends on the flow and the voltage, but isn’t the immediate outcome described. A ground fault is an abnormal condition and does not fit the normal setup for current flow.
